ROAD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 323,002, dated July 28,1885.

Application filed MitlK'll .7, i885. (N'o model.)

To all whom it may concern.-

Be it known that I, S. FRANK WELoH, of Mount Pleasant, in the county ofHenry and State of Iowa, have invented certain new and usefulImprovements in Road-W'orking Machines; and I do hereby declarethe'following to bea full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in road-working machines, theobject of the same being to provide improved means for conveying earthfrom the sides of the road to the center, leveling rough places,cleaning out old ditches, or filling ditches,'and other work of a likecharacter; and with thcse ends in view my invention cousists in ascraper-blade pivotally secured to a supporting-frame in 2Q horizontalangular adjustment, the support ing-frame being secured to crank-axlesin tilting adjustment.

My invention further consists in a scraperblade mounted upon wheels andprovided with a colter-guide to prevent slu'ing, loosening the earth,8m.

My invention further consists in certain features of construction andcombinations of parts, as will be hereinafter described, and

pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of the machine inperspective. Fig. 2 is a view in side elevation, one of the wheels beingremoved. Fig. 3 is a plan View, the

3 5 drivers seat being removed. Fig. 4 is an enlarged view of thescraper, showing the colter attachment; and Fig. 5 is an enlarged Viewof a portion of the scraper-blade and circle, showing the manner ofattaching the blade.

A is the main axle, or more properly a bar connecting two stubaxles, a.The tongue T is secured to the bar A, and extends rearwardly therefromfor the attachment of the scraper-blade, as will appear further on. Thestub-axles a are cranked, their inner ends being jo'urnaled to the bar Ain suitable bearings I), and their outer ends carrying thesupporting-wheels W. Operating-levers L are secured to the inner ends ofthe crank-axles a, and are provided with springactuated dogs d,whichengage toothed sector-bars R,se-

cured on the bar A or on the bearings b, attached to the bars A. Aspring-standard, X, carrying the drivers seat S, is secured to the bar Abetween the operating-levers L in such a position that the handles arewithin convenient reach of the driver when seated. Two hounds, h, aresecured to the under side of the bar A, one on each side of the tongue,and diverge from each other as they extend rearwardly. A circle or areof a circle, 0, preferably the latter, is attached to the tongue and tothe ends of the hounds h, thereby bracing the tongue and at the sametime securing the circle or are rigidly in position.

B is the scraper-blade, and it consists preferably of a curved metalsheet of suitable thickness provided with a steel edge. The blade isre-enforced by a number of ribs, K, bolted to its rear face. One of theribs K is located at the center of the blade, and is provided withrearwardly extending perforated lugs 1', through which one branch of aU-shaped bolt, D, passes. The ends of the bolt D are secured to the rearportion of the tongue T, and thus secure the scraper-blade thereto in ahorizontally swinging adjustment. Two of the ribs K are located adistance apart equal to the diameter of the circle or are 0, andterminate at their upper ends in fiat heads 1], 8c which extend beyondthe edges of the circle, and are provided with bolt-holes just outsideof the edges of said circle. A short bar, M, provided with correspondingperforations, is located on the upper side of the circle, and the headsE and bars M are drawn in snug contact with the circle by threaded boltsm, provided with draw-nuts m.

By means of the fastenings the scraperblade is locked in any desiredhorizontal anguc lar adjustment.

Other forms of fastening than that shown might be conveniently employedaclip, for

example, or yoke and thumb-nuts; hence I do.

not wish to restrict myself to the particular form shown.

A V-shaped frame, f, is secured to the rear faces of the two end ribs,K, in the ends of which frame an axle-rod, n, is secured. A rollingcolter, H, is secured on a sleeve, is, which latter is mounted on theaxle-rod n. The colter is 10- cated 011 the outer end of the sleeve k,and

rod or, to cause the colter to cut deeper or.

shallower and change its angular adjustment with reference to thescraper-blade when the angle of the latter is changed relatively to theline of draft. The framef is braced by a diagonal rod, 9. 1

The colter and colter supporting frame above described are located inthe rear of the scraper-blade; but in many instances it may be founddesirable to locate them in advance of the cutting end of thescraper forthe purpose of cutting and loosening the earth, to give thescraper'blade a better hold and to lessen the draft by loosening theearth, and at the same time prevent the sluing of the blade as before. Ahanger-strap, J, is bolted to the under side of the tongue for thepurpose of lowering the draft sufficiently to take all neckdraft of thetongue T, and a foot-rest, P, is at tached in convenient position to thetongue.

By means of the operating-levers L the crankaxles a are rotated, and thescraper blade thereby tilted to the right or left, elevated ordepressed, as may be desired, and by means of the circle or are C, thepivotal support D, and the devices for locking the blade to the circlethe blade may be swung to work right or left handed, set at any angledesired to the line of draft or at right angles thereto, while thecolter H prevents the sluing of the blade and cuts a guide line for thesecond passage of the scraper in cases where it is used to excavate, andadds very little to the drag.

It is evident that slight changes may be made in the form andarrangement of the several parts described without departing from thespirit and scope of my invention; hence I do not wish to limit myselfstrictly to the construction herein set forth; but,

Having fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. -In a road-working machine, a scraper blade pivotally secured to asupporting-frame in horizontal angular adjustment, and adapted to bevertically adjusted by means of rocking axles, substantially as setforth.

2. The combination, with a scraper-blade secured to a supporting-framein horizontal angular adjustment, of a pairof crank-axles secured to thesupporting-wheels, and means for rocking the axles and thereby tiltingand vertically adjusting the scraper-blade, substantially as set forth.

3. The combination, with a bar having axles j ournaled to each end andsupporting-wheels mounted on the axles, of the tongue secured to thesaid bar, the scraper-blade pivotally secured to the tongue, the circleor are secured to the tongue and bar, and means for locking thescraper-blade to the circle or are in horizontal angular adjustment,substantially as set forth.

4. In a road-working machine, the combination, with a supporting-frame,of a scraperblade pivotally secured to the supportingframe by a U-shapedbolt, one of the legs of said bolt acting as a brace to support thelower end of the other leg, substantially as set forth.

5. The combination, with a vertically-adjustable supporting-frame and ascraperbladc secured thereto in horizontal angular adjustment, of acolter journaled in bearings secured to the scraper, substantially asset forth.

6. The combination, with a scraper secured to a supporting-frame inhorizontal angular adjustment, of a rolling colter secured to thescraper-blade in horizontal angular adjustment, substantially as setforth.

In testimony whereof'I have signed this specification in the presence oftwo subscribing witnesses.
